<p>I don’t think most schools recalculate GPAs - think of the work to recalculate GPAs for 10K+ applying freshman. I do believe many very competitive schools will recalc. I think most schools just eyeball the GPA, class rigor and HS profile to get an idea of how they would do as a student at the college. And not all high schools will weight harder classes, nor do most colleges care about ECs. Look at the Common Data Set, section C7, for schools in which you are interested to see what you need to concentrate on.</p>
